TRANSCRIPT
Passion for Precisionin the measurement of Solar Radiation and Atmospheric Properties
Our story begins when the Dutch pharmacist Petrus Jacobus
Kipp buys a pharmacy shop in the old centre of Delft, the
Netherlands. Shortly after that he starts an instrument
business and becomes an important adviser to the Royal
Academy (now the Delft University of Technology).
Since 1830
In 1844 he designs a new constant-flow gas
generator, which is successfully used all over the
world. This “Kipp Generator” is still an icon in the
world of Chemistry and remains part of our company
logo today. In 1866 his two sons continue the
business under the name Kipp & Zonen (‘Sons’).
By 1927 the extensive catalogue of scientifi c
instruments included laboratory glassware,
galvanometers, electronic chart recorders,
analytical instruments, telephones, and the
first ‘Solarimeters’. The company grew
steadily over the next decades and changed ownership
several times, but by 2004 Kipp & Zonen was back in private
ownership and in 2006 moved to new facilities at the Delft
technology park.
Kipp & ZonenToday, Kipp & Zonen focuses on designing, manufacturing,
and marketing, class-leading, high quality instruments for
the measurement of solar radiation and atmospheric
properties. To support our customers worldwide we
have sales offices in France, Singapore and the USA,
and a network of exclusive distributors in more than 40
countries.
Ready for the future
Over the last century the Earth’s climate has changed
significantly, on both global and regional scales and continues
to do so. Climate change is a major threat to eco-systems, food
production, water resources and to our way of life.
Precise long-term measurements of the radiation budget and
atmospheric properties are fundamental to under-standing
the Earth’s climate system and improving weather and climate
forecast models.
Kipp & Zonen provides the widest range available of
instruments to meet these needs, at levels of price and
performance to suit all applications and fully traceable to
international standards.
Passion for PrecisionOur mission is to satisfy the fundamental need to monitor
atmospheric properties related to climate change, classical
meteorology, climatology, renewable energy and the
available water budget. To achieve this we support signifi cant
research and development by off ering the highest quality
equipment, solutions and support for these markets.
Everyone involved in these subjects is passionate about
them. We share this desire to improve mankind’s scientifi c
knowledge of the world that we live in and to contribute to
the exploration of our future climate and its eff ects on eco-
systems and bio-diversity.
Therefore it is with passion that we develop, manufacture
and market our products worldwide. Kipp & Zonen is a
business, but we also believe that what we do is of genuine
benefi t to the global community. We hope that you will join
us in our passion for precision.
Our Capabilities
Kipp & Zonen is a leading authority in the measurement of
solar radiation and atmospheric properties and is widely
recognized for expertise, quality and service. We support
signifi cant research and development and maintain close
links with the scientifi c community and international bodies
such as the World Meteorological Organisation (WMO).
We take part in scientifi c comparisons and fi eld campaigns
and are involved with the creation of international
standards. Kipp & Zonen is certifi ed to ISO 9001:2008 and
is a founder member of the Association of the Hydro-
Meteorological Equipment Industry (HMEI). We have
in-house facilities for research, development, software,
manufacture and testing, and we can provide customer-
specifi c solutions.
High quality customer support is essential to our business
and includes provision of spare parts, repair, service and
calibration. Our experts are available to give assistance and
advice on the most appropriate equipment for an
application. For our more complex products we off er on-site
installation, commissioning and training.
Professionals in these scientific disciplines strive to
understand the infl uences on our weather (short-term) and
climate (long-term), on scales from very local to country-
wide and global. They use a mixture of software models and
skilled data interpretation to make forecasts. However, this
mainly depends upon predicting the future from what
happened in the past and, as many people in the world are
now aware, this is no longer reliable.
Improved forecasting requires good quality and reliable
real-time data from widespread networks of instruments
around the globe, and a key part of this is solar radiation.
Kipp & Zonen manufactures a full range of instruments for
monitoring solar, sky and terrestrial radiation; from small,
light, models suited to entry-level weather stations and
portable fi eld use up to the very best equipment available.
Pyranometers, pyrgeometers, net radiometers, total-UV and
sunshine duration sensors - we make them all, plus a
comprehensive range of accessories. Pyrheliometers
measure only the radiation coming directly from the sun
and, of course, Kipp & Zonen makes some of the best
automatic sun trackers to mount them on. All this data needs
to be acquired and stored – we have solutions for that too.
Kipp & Zonen instruments are the choice of meteorological
organisations and climate researchers around the world who
demand quality, reliability and performance.
Meteorology and Climatology
A major concern is the environmental impact of cities and
industrialisation on the environment and on the population,
particularly with respect to air quality. In the ‘developed’
world things are improving but in many emerging economies
the situation is rapidly getting worse. Volcanic emissions
and deforestation by fi re add to problems in the Asia-Pacifi c
regions.
Many factors eff ect bad urban air quality and ‘smog’ events,
including; solar radiation, atmospheric aerosols and the
temperature profi le. In order to give the public advance
warning of hazardous air quality it is necessary to have
accurate real-time information. Kipp & Zonen has innovative
instruments using the latest optical, microwave and laser
(Lidar) technologies.
Another health concern is the amount of harmful UV
radiation reaching the ground. To report the UV-Index
accurately for public information requires quite
sophisticated instruments. Only Kipp & Zonen produces
both these and the software necessary to correct the data for
atmospheric eff ects.
‘Holes in the Ozone layer’ are areas of stratospheric Ozone
depletion. These are indicators of the general health of the
atmosphere and let through more
harmful UV to the ground. They
are not confi ned to the North
and South Poles. The Kipp &
Zonen ‘Brewer’ spectropho-
tometer forms the basis of
the global Ozone and UV
database.
Public Health and Environment
Renewable EnergyThe limited supply and rising prices of traditional energy
sources, together with the increasing awareness of climate
change, have resulted in rapid development of alternative
energy sources. Recent years have seen exponential growth
in the wind and solar energy markets.
Kipp & Zonen provides a complete range of solar radiation
measuring instruments for both photo-voltaic (PV) and
thermal solar energy systems. By measuring the available
incoming solar energy the effi ciency of the system can be
calculated, and the need for cleaning or other maintenance
can be assessed.
Solar Farms
Southern Europe is one of the leading regions of the World
when it comes to collecting solar energy. ‘Solar Farms’ are
becoming a common sight, with hundreds of acres covered
by PV arrays, and the effi ciency of these must be monitored.
Our CMP series pyranometers fulfi ll the requirements of the
IEC 60904 standard for PV testing and are widely used for
measuring and comparing all types of PV systems.
Kipp & Zonen sun trackers, pyrheliometers and pyrano-
meters are installed in networks to ensure the precise and
objective measurement of incoming solar radiation.
The data is used for solar
energy research and for
‘Sun Prospecting’ (the
determination of
optimal locations).
Solar energy
professionals rely
on Kipp & Zonen products.
Over the past 15 years industrial scientists and engineers
have become familiar with Kipp & Zonen products. Many
industrial applications require testing of products and
materials for the eff ects of environmental exposure that
could be experienced in use world-wide. This can be done at
outdoor weathering facilities or in special climate chambers.
Solar radiation is a large part of that exposure and this is our
specialty.
Tested to Any Extreme
The Automotive Industry is a large and most prestigious
mass-production industry. Heat-load testing and the eff ects
of UV radiation are conducted on complete vehicles,
components and materials. To ensure controlled conditions
much testing is carried out in climate chambers with
solar radiation simulated by high power metal-halide or
tungsten-halogen lamps.
Pyranometers are used to monitor the light intensity
(irradiance) at various positions within the test environment
as well as the spectral power distribution and its uniformity
within a reference area. ‘Accelerated’ testing is often done,
with intensities and temperatures several times the
maximum natural levels. Our High Temperature Pyranometer
was developed in close cooperation with our industrial
partners to be the World’s most reliable pyranometer for
measurements in such extreme conditions.
To any extreme, Kipp & Zonen instruments will deliver
reliable performance.
Industry
Light is essential for plant growth. It drives the process of
Photosynthesis, which converts water and Carbon Dioxide
into Glucose and Oxygen. This chemical process is the
driving force in plant development. Diff erent parts of the
light spectrum have specifi c infl uences on plant physiology,
such as leaf development, stem elongation, and the
biological clock.
The Netherlands has a reputation for effi cient production of
vegetables, fruit and fl owers. Being one of the most densely
populated countries in the world, there is a constant need to
improve horticultural production methods that effi ciently
use the scarce land available.
Optimizing the Measurement of the Light of Life
Accurate measurement of solar radiation and Photo-
synthetically Active Radiation (PAR) is a necessity to control
the complex artifi cial environments within the numerous
greenhouses in our country. Kipp & Zonen pyranometers are
used in the majority of meteorological stations which
provide the inputs for greenhouse climate control systems,
in which both natural sunlight and artifi cial lighting is used.
Our PAR sensors are employed to monitor the infl ux of PAR
radiation from these sources.
Advances in lighting systems for horticulture provide
improved control and quality of plant growth. Kipp & Zonen
is in constant cooperation with agricultural companies and
universities to develop and improve radiometers to meet the
measurement requirements of the future.
Agriculture
The Earth’s atmosphere is a complex system of dynamic
turbulent processes and changing chemical composition.
Accurate data about the atmosphere is of vital importance
for research into properties such as boundary layer evolution,
aerosols, pollution development, clouds, and more.
Traditional measurements are made ‘in situ’ using
instruments on towers, attached to balloons or in aircraft.
Remote sensing instruments do not require contact with the
medium being measured and are normally ground or satellite
based. Kipp & Zonen supplies a range of products using
optical and microwave remote sensing technologies.
Investigating the Atmosphere at the Speed of Light
Light Detection and Ranging (Lidar) uses Laser pulses
transmitted into the atmosphere. A proportion of the energy
is refl ected back by molecules and aerosols to the receiving
telescope, which collects the radiation and focuses it onto a
sensitive detector.
The time delay between the transmitted pulse and any part
of the return signal is equivalent to distance (range). This
ability to derive profi les of atmospheric
properties with excellent temporal
and spatial resolution is the key
advantage of the Lidar technique.
Kipp & Zonen exclusively represents
Lidar systems designed and manufactured
by Raymetrics S.A. of Greece, which are the
result of years of research and co-operation
within international campaigns.
They are compact, portable, turn-
key, cost-eff ective and designed
for continuous outdoor operation.
Remote Sensing
There is an ever-growing need for fresh water, for people,
animals, agriculture and industry. Life depends on water and
in certain parts of the world climate change severely impacts
upon its availability and usage. Monsoons fail, rain patterns
shift and fertile areas become barren.
The challenge for hydrologists is to gain an accurate insight
into the world’s water resources, and this requires
continuous monitoring of rainfall, river run-off , evaporation,
and surface energy fl uxes.
Our turn-key Large Aperture Scintillometer (LAS) Evapo-
Transpiration (ET) systems are specifi cally designed for
Earth energy balance studies. These systems offer
measurement scales up to 10 km for atmospheric turbulence,
sensible heat fl ux and ET. This is a major advantage over
point measurement techniques, making them ideal for the
ground validation of satellite measurements.
Monitoring the World’s Water Resources
River basins and deltas support the supply to local
populations of fresh water for both consumption and
irrigation purposes. Monitoring them is a signifi cant part of
water resource management. ET is an important indicator of
plant and tree condition and rates of growth and the data
can serve as an input for hydrological models, drought
prediction and crop yield forecasts.
